Abstract: Background and objective As many lung cancer patients lose surgical possibility, it is important to explore new treatments to improve prognosis. The study is to observe adverse reactions and therapeutic effects of cryosurgery combined iodine-125 seeds implantation in treating advanced lung cancer patients. Methods One hundredforty unresectable pulmonary cancer patients received percutaneous cryosurgery and iodine-125 implantation under CT guidance. Patients were followed-up 1 year, with CT scan, therapeutic effect, complications and survival time monitoriy. Results The one hundred forty patients successfully received cryosurgery combined with iodine-125 seed implantation and one-year follow-up. The patients with 6 m posttreatment had complete remission (CR) of 93.4%, partial remission(PR) of 70.1%, stable disease (SD) of 7.4%, and progressive disease (PD) of 5.7%. The half-year and one-year survival rates were 94.3% and 65.7% respectively. The average KPS was improved from 66.9 to 76.3. Conclusion Cryosurgery combined with iodine-125 seed implantation is effective in treating unresectable lung cancer, providing a promising treatment protocol for unresectable lung cancer patients.

Abstract: The structure and magnetic properties of Fe76.5Si13.5B9Cu1 alloys with a nanocrystalline (NC) bcc Fe(Si) phase trom about 23 to 46 nm in diameter, which were first formed into amorphous ribbons and then annealed at various temperatures between 703 and 773 K, have been investigated. At annealing temperatures from 703 to 748 K, the single NC bcc(Si) phase is obtained in the crystallized alloys. The grain size and the Si-content in the NC bcc Fe(Si) phase for the alloys annealed at different temperatures are presented. The soft magnetic properties and the saturation magnetostriction for the alloys with the NC bcc Fe(Si) phase are also measured. The results show that, the saturation magnetizotion and the permeability are improved for the alloys with only the NC bcc Fe(Si) phase and become better with decreasing of the NC bcc phase size, and the saturation magnetostriction declines for the alloys with increasing Si-content in the NC bcc Fe(Si) phase.

Chinese Journal of Lung Cancer , 2010,
Abstract: Background and objective Most lung cancer patients present an advanced stage at diagnosis without suitable surgical chances. Cryotherapy has been applied to the advanced lung cancer with safety and effectiveness. The aim of this study is to analyze the most common complications that occur after percutaneous cryoablation when applied to advanced lung cancer. Methods Total 644 lung cancer patients had been treated with percutaneous cryoablation guided by ultrasound and/or CT scan. The cardivascular and respiratory complications were monitored. Results Complications were relatively minor and could be controlled with routine methods. Serious complications included cardiac arrest and hemopneumothorax, and thus preventative steps should be taken. Conclusion Percutaneous cryoablation for lung cancer is a simple, effective and relatively safe method, but attention should be paid to the possible complications during cryoablation.

Chinese Journal of Lung Cancer , 2010,
Abstract: Background and objective Lung cancer is one of the most commonly occurring malignancies and frequent causes of death in the world. Cryoablation is a safe and alternative treatment for unresectable lung cancer. Due to the lung being gas-containing organ and different from solid organs such as liver and pancreas, it is difficult to achieve the freezing range of beyond the tumor edge 1 cm safety border. The aim of this study is to examine the effect of different numbers of freeze cycles on the effectiveness of cryoablation on normal lung tissue and to create an operation guideline that gives the best effect. Methods Six healthy Tibetan miniature pigs were given a CT scan and histological investigation after percutaneous cryosurgery. Cryoablation was performed as 2 cycles of 10 min of active freezing in the left lung; each freeze followed by a 5 min thaw. In the right lung, we performed the same 2 cycles of 5 min of freezing followed by 5 min of thawing. However, for the right lung, we included a third cycle of consisting of 10 min of freezing followed by 5 min of thawing. Three cryoprobes were inserted into the left lung and three cryoprobes in the right lung per animal, one in the upper and two in the lower lobe, so as to be well away from each other. Comparison under the same experimental condition was necessary. During the experiment, observations were made regarding the imaging change of ice-ball. The lungs were removed postoperatively at 3 intervals: 4 h, 3 d of postoperation and 7 d of postoperation, respectively, to view microscopic and pathological change. Results The ice-ball grew gradually in relation to the increase in time, and the increase in number of cycles. The size of the cryolesion (hypothesis necrotic area) in specimens, over time, became larger in size than the size of the ice-ball during operation, regardless of whether 2 or 3 freeze-thaw cycles were performed. The area of necrosis was gradually increased over the course of time. The hypothesis necrotic area was equal to necrosis area 3 d after cryosurgery. Conclusion Percutaneous cryoablation of the lung can achieve complete ablation of target tissue. The freezing technique may be different depending on the individual circumstances of each tumor. In technology, 3 freeze-thaw cycles are recommended, and the range of cryoablation’s effective diameter may be not necessarily beyond the tumor edge at least 1 cm safe border during cryosurgery.

Abstract: Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in a variety of evolutionary studies. In this study, we determined the complete mtDNA of Bean goose (Anser fabalis), which is 16,688 bp long and contains 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. The arrangement is similar to that of typical Anseriform species. All protein-coding genes, except for Cyt b, ND5, COI, and COII, start with an ATG codon. The ATG start codon is also generally observed in the 12 other Anseriform species, including 2 Anser species, with sequenced mitochondrial genomes. TAA is the most frequent stop codon, one of three–TAA, TAG, and T- –commonly observed in Anseriformes. All tRNAs could be folded into canonical cloverleaf secondary structures except for tRNASer(AGY) and tRNALeu(CUN), which are missing the dihydrouridine (DHU) arm. The control region of Bean goose mtDNA, with some conserved sequence boxes, such as F, E, D, and C, identified in its central domain. Phylogenetic analysis of complete mtDNA data for 13 Anseriform species supports the classification of them into four major branches: Anatinae, Anserinae, Dendrocygninae and Anseranatidae. Phylogenetic analyses were also conducted on 36 Anseriform birds using combined Cyt b, ND2, and COI sequences. The results clearly support the genus Somateria as an independent lineage classified in its own tribe, the Somaterini. Recovered topologies from both complete mtDNA and combined DNA sequences strongly indicate that Dendrocygninae is an independent subfamily within the family Anatidae and Anseranatidae represents an independent family. Based on the results of this study, we conclude that combining ND2, Cyt b, and COI sequence data is a workable solution at present for resolving phylogenetic relationships among Anseriform species in the absence of sufficient complete mtDNA data.

Abstract: For a compact millimeter wave imaging system it is very important to design every component into small size, for the components in a millimeter wave system are usually much larger than those in an optical imaging system due to rela-tively long wave lengths. In this paper, we suggest a kind of binary diffractive lens (BDL) designed using double nega-tive materials (DNG) as the objective lens for a millimeter wave imaging system. The DNG-BDL has not only the ad-vantage of low profile but also small f number, which will be benefit for constructing a compact millimeter wave imaging system. Several DNG-BDL are designed and analyzed using the FDTD method. The numerical results of the focal plane field of the DNG-BDL are presented, which show that the DNG-BDL with small f number has relatively better focusing characteristic than that of a double positive BDL with same f number.

The conjugates of monoclonal antibodies and nanoparticles, including quantum-dot(QD), offer significant advantages over conventional fluorescent probes to image and study biological processes. The extend stability, intense fluorescence and low toxicity of QDs are well suited for biological applications. In the present study, we used QD-conjugated anti-glucose-regulated protein 78(GRP78) antibody to examine the gene expression in prostate cancer cells under the unfolded protein response (UPR). QDs have got unique, simple and fast properties over current diagnostic techniques such as peroxidase-based immunohistochemical staining procedures, therefore the nanocarrier-conjugated antibody fragment has potential to become a new therapeutic tool for cancer diagnosis and treatment.
